Common problem. In your hosts file you must have all machines with their
IP and domain name. This must include the local machine and IP! But from

Only if you are also running a server on the local host, surely?

If you also want the client to run the test (at the same time as
handling all the server replies ...), you can always run the test
locally using the run command (assuming that you are running in GUI
mode).

my experience it is advisable not to run this in client-server mode but
to start each server separately from the command line (jmeter -n).

Indeed, it can place a heavy load on the client ant the network
connections to the client.

The current release has a statistical mode (responses are accumulated
in some way and sent as summaries), but I've not tried this.

Cheers

Subject: JMeter JDBC benchmark + Remote Testing

I've setup a jmeter JDBC transaction benchmark, and I'd like to spread
the work across multiple JMeter hosts.  It's a simple test that works on
one machine (without remoting), but I'm running into problems when I try
to execute "Remote Starts".

So, machine 1:  Windows XP - I start the jmeter-server.  That's fine.

Then I go to GUI, and execute Remote Start 127.0.0.1.  Nothing happens.

Stack trace from server console follows:

Exception in thread "Thread-2" java.lang.NullPointerException

e.java:315)
        at java.lang.Thread.run(Unknown Source)


Anyone using JMeter and remoting with JDBC samplers?  I'm not sure
what's going on.  Maybe the server doesn't have the JDBC drivers loaded.

 Again, the test runs fine without remoting.

Thanks,

-Dave
